There are many 802.11g Wi-Fi devices around us and they are making the 2.4 GHz frequency extremely crowded. Worse yet, only three non-overlapping 

channels are available and they may conflict with each other to cause network traffic jam.

The ZyXEL NWA1123-NI 802.11 a/b/g/n Dual-Radio PoE AP consists of 2.4 GHz and 5 GHz dual-band radio to match the concurrent Wi-Fi services with either 

frequency. As more and more recent mobile or laptop devices support both 2.4 GHz and 5 GHz bands, users can choose 5 GHz as the first priority for default 

searching and balance heavy network loading with the 2.4 GHz band.

The higher frequency of the 5 GHz band provides a shorter signal range compared to the 2.4 GHz band with the same transmit output power. The NWA1123-NI 

consist of high 5 GHz transmit output power can boost the 5 GHz signal range, providing signal coverage equal to the 2.4 GHz wireless network. Therefore, the 

complexity of deployment can be considerably reduced. 

In different public environments, the administrators may use VLAN switches to separate the traffics from different type of users; as such different group of users 

may need independent Wi-Fi security settings too. The ZyXEL NWA1121-NI provides up to 8 SSIDs and the NWA1123-NI provides up to 16 SSIDs (dual-band) to 

map the VLAN security level settings to classify users for different application services, such as public Internet access or restricted Web contents. This function 

allows businesses to make consistent user management in wireless edge.
